How to Use a Generator with a Travel Trailer

What’s better than a day trip to the beach? A weekend getaway. If you are looking for some peace, there is nothing more relaxing than spending time in your trailer at the campground.

However, what happens when you want to cook dinner or take a shower? You need electricity. Fortunately, powering your travel trailer with solar panels is easier than it sounds.

Read on to learn how to use a generator with a travel trailer so you can enjoy your next camping experience.

What Size of Generator Do I Need for a Travel Trailer?

The size of the generator you need for your travel trailer will depend on how many appliances you want to power. If you use a small refrigerator, a few lights, and the pump for your water tank, then a 2000-watt generator should do the trick.

However, if you have a larger refrigerator, air conditioner, and microwave, you will need a more powerful generator. A 5000-watt generator should be able to handle all of your needs.

How to Choose the Right Generator for Your Travel Trailer?

You need to consider some factors before buying the first generator you come across.

Fuel Source: Gas or Propane? You will want to make sure the generator you buy can run smoothly with whatever fuel source you use.

If you plan on using a propane tank, then a small 20 lb. propane tank should be able to power all of your appliances for around 10 hours.

However, if you want to use gasoline for your generator, make sure you buy a large enough gas tank for your unit.

2-stroke or 4-stroke? Most small generators are 2-stroke, while larger generators are 4-stroke.

This means that the smaller ones have parts that move back and forth when they run. A two-stroke generator will also need to be mixed with oil, while a four-stroke does not.

Do you need a wheel kit? If you plan to move your generator around often, you will want to buy one that comes with a wheel kit. This will make it much easier to transport.

Noise Level

This is an important factor to consider if you plan on using your generator near your trailer. A loud generator can be a real nuisance, especially if you plan on sleeping nearby.

Fuel Efficiency

How much will the generator cost to run? You don’t want to pay more for fuel than necessary, so make sure you choose a generator that is energy efficient.


What will your appliances need? You should know the wattage of all of your appliances before purchasing a generator.


How often will you be using your generator? If you plan on using it often, it will need to be strong and durable so that it can last a long time.

Once you have chosen the right generator for your travel trailer, it is time to learn how to use it. Here are a few simple steps:

  • Connect the generator to your trailer: this is probably the easiest step. Just plug the generator into the 120-volt outlet on your trailer.
  • Turn on the generator: now that the generator is connected, turn it on by flipping the switch on the front or side of the unit.
  • Set the voltage: most generators have a voltage selector switch. You will want to set this to match the voltage of your trailer. For example, if you use a 30 amp RV, you will want to set the switch to 120 volts.
  • Start up your appliances: now that the generator is up and running, you can begin powering your appliances. Just make sure they are turned off before connecting them to the power source.
  • Turn off your appliances: after using any appliance, make sure you turn it off. This will help reduce energy costs and prolong the shelf life of your batteries.
  • Shut down the generator: when you are finished using the generator, ensure you turn it off by flipping the switch to the “off” position.

Now that you know how to use a generator with a travel trailer, you can safely power all of your appliances without having to worry about going off-grid.

FAQ’s on how to Use a Generator with a Travel Trailer

Can I Plug My RV into a Generator?

Yes, you can plug your RV into a generator. Just make sure that the voltage selector on your generator matches the voltage of your RV. If it does not match, then there is a chance that your appliances will fry and become unusable. For example, if the voltage selector on the generator is set to 120 volts, but the RV is using a 30 amp system, you will fry your RV’s electrical systems.

Can You Drive Your RV with the Generator Running?

Yes. However, you should never run your generator while driving unless it is an emergency. You can drive with the generator attached to your RV, but keep in mind that this will drain your battery faster. It’s best not to use a generator when driving because they are too loud for safe operation on the road.

How Much Power Does an RV Generator Produce?

It depends on the size of the generator. Most RV generators range from 2,000 to 6,000 watts. This is more than enough power to run all of your appliances at once. However, if you have a high-wattage appliance, like a microwave, you may need to buy a generator that provides 7,000 watts or more.

Why Do I Need a Generator for My Travel Trailer?

A generator is a necessary piece of equipment for any travel trailer. Without it, you will not power any appliances or electronics. This can be a real inconvenience, especially if you are camping in an area without electrical hookups. A generator ensures that you have all the power you need while on the road.

When it comes to using a generator with your travel trailer, there are many benefits. One benefit is that you won’t need to rely on the electrical hookups at RV parks.

Instead, you can use your generators to power all of your appliances whenever and wherever you want to camp. Just make sure that you use the right kind of generator for your trailer and know how to use it safely.
